RADIATOR.

To all whom it may concern.

Be it known that I, NATHAN FRANKLIN, a citizen of the United States, and resident of ilwaukee, in the county of Milwaukee and State of Wisconsin, new and useful Improvements in Radiators; and I do hereby declare that the followthereof.

My invention relates to new and useful improvements in radiators, more particularly of that type adapted for use in connection with the cooling systems of automobile or other power plants, and comprising pairs of elongated plates extending transversely of the plane of the body of the radiator, the longitudinal edges of each pair of plates being connected together to define narrow passageways rendered tortuous in'nature by providing sinuous cross sections for the plates to procure a desired expanse of co0ling surface between the pairs of plates.

It is in general the object of my invention to improve the construction of radiators of this character, and it my object to provide an arrangement efl'ectmg an increased expanse of radiating surface whereby to increase the cooling efficiency of the radiator. Itis further my object in this connection to provide such increased radiating surface without unduly obstructing the air spaces between the passageway-forming pairs of plates whereby to permit free passage -of the air through the radiator, and free access to the spaces between theplates for the purpose of repair.

It is further my object to provide an arrangement wherein the sinuous cross sectional shaping of the passage plates permits ready expansion. and contraction of the various portions of the plates incidental to changes of temperature.

With the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of the parts as hereinafter described and'defined by the appended claim,

in the accompanying drawings:

Fig. 3 is a vertical transverse sectional view. through the radiator mesh on the plane Fig. 2, and

Fig. 4 is a horizontal sectional view of a portion of the radiator mesh on the plane indicated by the line 4-4 of Fig. 2.

Referring now more particularly to the accompanying drawings, A and B designate respectively the upper and lower heads of a radiator structure of the automobile type embodying my invention, pairs of mating plates 5, 5 6, 6 and 7, 7, etc., extending vertically disposed transversely of the general plane of the radiator body whereby to provide theusual air cells therebetween, the passageway defined by each pair of plates communicating in the usual-manner With the radiator heads A and B. The air cells between pairs of passage forming plates are divided by flat plates 8, foraminous in na ture.

My invention resides in the particular cross sectional shaping of the plates to procure an increased radiating surface thereof and to lengthen the path of travel of the water or other fluid to be cooled with respect to said radiating surface. Thus, each of the plates is provided with a series of regularly spaced bends 8 extending transversely therethrough and directed outwardly with respect to the passageway formed between sides of these bends slightly spaced to form water chambers extending transversely of the planes of the plates, and the end portions of the bends are crimped together forming resultant shoulders 25 which close the ends of these water chambers. The ed e portions of each pair of plates are also 0%- set toward each other for mutual engagement, forming resultant shoulders M which close the sides of the main passageway formed by the pair of plates. The bends thereforedefine transverse hollow ribs on the walls of the passageway formed by each pair of plates and these bends or ribs form expansion or contractionsections compensating for the changes in temperature to which the plates are subjected, as will be noted particularly by reference to Fig. 2. The plates are also provided between each pair of bends s with .a pair of outwardly struck portions '0 extending longitudinally between these heads, the plates being each pair of plates, the
